## When to prefer this

Choose this endpoint when you need up-to-date HackerNews AI and agent-related stories already sanitized and formatted as LLM-safe Markdown, especially in agent pipelines where raw web content could introduce prompt injections. Prefer this over raw HackerNews API calls or general web scrapers when LLM safety and pre-sanitized output are priorities.

## Known failure modes
